GAS-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 506,759, dated October 17, 1893.

Serial No. 470,101. (No model.)

To all whom it may concern:

Be it known that 1, AUGUST WIENEOKE, of Brooklyn, Kings county, New York, have invented an Improved Gas-Burner, of which the following is a specification.

This invention relates to a gas burner in which the gas is automatically turned off when blown out or not lighted, or when the supply of gas is temporarily suspended.

In the accompanying drawings: Figure 1 is a longitudinal section of my improved gas burner showing the cock closed; Fig. 2 a horizontal section on line w, m, Fig. 1,looking npward; Fig.' 3 a section similar to Fig. 1, showing the position of the parts with the cock open; Fig. 4 a detail vertical section through the plug of the cock and Figs. 5 and 6 cross sections of Fig. 4, showing the sleeve in different positions.

The letter a, represents the gas supply pipe provided with stop cock I), and burner c, as usual. In close proximity to burner 0, there is contained in asuitable casing d, a vessel e, containing mercury. A bent wire f, partly projecting over the flame and dipped into the mercury serves to transmit the heat from the flame to the latter. Above the mercury there is contained within the vessel e a float g, connected at one end to a detent spring lever h, pivoted to casing d, at h. The detent of lever h, engages indentations z", of a wheel 4., fast on spindle 2' The spindle i is by gear wheels i j, intergeared with spindle j, which in turn by gear wheel 7' is intcrgeared with wheel in, loose on spindle in. The gear wheel k, is provided with a click k engaging a ratchet wheel k fast on spindle is.

The plug b, of cock b, is surrounded by a revolving sleeve m, one quarter of which is cut away. A pin b on cock 19, engages the sleeve m, and revolves the same when the cock is opened. To the sleeve m, there is attached a spindle n, which by gear wheels n, 70 is intergeared with spindle is. To the spindle n, is connected the inner end of a 45. coiled spring 0,the outer end of which is connected to casing d.

The operation of the device is as follows: When the cock I), is opened, the sleeve m, is revolved to compress the spring 0, and also to revolve spindle 70, which is thus put under tension to revolve in the reverse direction. This tension is by click k transmitted to wheel 10, and thence by the train of gearing to the wheel 1'. As long as the gas is lighted and the mercury expanded (Fig. 3) the wheel 1;, is locked in position by the detent lever h, and thus the gas will be properly fed to the burner. But when the light is for some reason extinguished, the mercury will contract and the float 9, falls to tilt lever h, and liberate wheel 2', (Fig. 1.) The wheel '5, having been put under tension as described, will now revolve, to close the cock. If the cock is closed by hand the pin 12 will not take the sleeve m, with it, but the latter will be revolved by the spring 0, as soon as the mercury has cooled snfficiently to release wheel 11. The vessel 6, should be only partly filled with mercury, so that the latter may freely expand 7o under the ordinary temperature of the room, without acting upon the float.

What I claim is 1. The combination of a burner with a supply cock, a surrounding sleeve m engaging the 7 same, a spring 0 secured thereto, a train of gearing, a wheel '0', a lever h, a float and a column of mercury in proximity to the burner and operating the float, substantially as specified.

2. The combination of burner c, with vessel e, containing mercury, aheat transmitting wire f, a float g, and a supply cock b, operated by such float, substantially as specified.

AUGUST WIENECKE.
